Lightning Bundle Configurations Available in the Developer Console
Configurations make it easier to create a component or application for a specific purpose, like a Lightning page or Experience Builder site page, or a quick action or navigation item in Lightning Experience or Salesforce mobile app. The New Lightning Bundle panel in the Developer Console offers a choice of component configurations when you create an Aura component or application bundle.
Configurations add the interfaces required to support using the component in the desired context. For example, when you choose the Lightning Tab configuration, your new component includes implements="force:appHostable" in the <aura:component> tag.
Using configurations is optional. You can use them in any combination, including all or none.
These Aura component bundle configurations and Lightning application bundle configurations are available in the New Lightning Bundle panel.
For details of the markup added by each configuration, see the respective documentation for those features.
